A calibration method and device for antenna array

An antenna array calibration method and device, including: the first target antenna of the antenna array transmitting signal. When the second target antenna receives the signal, it calculates the calibration compensation value of each transmission channel in the first target antenna and each receiving channel in the second target antenna. After the channel compensation, each transmission channel in the first target antenna is compensated. The amplitude phase response in the amplitude phase response is consistent and the amplitude phase response of each receiving channel in the second target antenna is consistent; the second target antenna sends the signal, and the first target antenna receives the signal, calculates the calibration compensation value of each transmitting channel in the second target antenna and the receiving channel in the first target antenna, and after the channel compensation, the second target antennas are sent to each other. The amplitude and phase responses of the channel are consistent and the amplitude and phase responses of the receiving channels in the first target antenna are consistent. In the embodiment of the invention, the antenna array is added to antenna dummy or radio frequency coupling device, and the amplitude phase response of all antenna transmission channels is consistent and the amplitude phase response of the receiving channel is consistent, thus the consistency calibration of the antenna array is realized.
